anthraquinone moiety is formed by the following intramolecular electron transfer, after the redox quenching of the excited state: [ReI(aq−2−CO2)(2,2′-bipy.)(CO)3]−⇌[ReI(aq−2−CO2.)(2,2′-bipy)(CO)3]− The photophysics, particularly the absence of a ReI-to-anthraquinone charge-transfer excited state photochemistry, is discussed in terms of the electrochemical and photochemical results.
(OC-6-33)-(2,2'-bipyridine-κN1,κN1')tricarbonyl(9,10-dihydro-9,10-dioxoanthracene-2-carboxylato-κO)rhenium (fac) 的光物理和光化学性质-[ReI(aq-2-CO2)(2,2'-bipy)(CO)3]) 进行了研究,并与游离配体 9,10-dihydro-9,10-dioxoanthracene-2-carboxylate ( = anthraquinone-2-carboxylate) 和其他含有 (2,2'-联吡啶) 三羰基铼 ([Re(2,2'-bipy)(CO)3]) 部分的羧基配合物。蒽醌衍生配体(λexc 337 或 351 nm)及其复合物的闪光和稳态辐照表明,后者的光物理学主要由 Re-to-(2,2'-bipyridine) 电荷引发的过程控制-转移激发态和以 2
